10 Claims.

This invention relates to new and useful improvemcnts in drilling machines and the primary object of the present invention is to provide a machine for drilling holes under pavement or concrete so that pipe lines may be placed under the street without breaking the pavement or concrete.

Another important object of the present invention is to provide a drilling machine that may be lowered to and from any depth up to four feet without the necessity of submerging the machine into a ditch.

Yet another object of the present invention is to provide a drilling and boring machine including a wheeled frame and a vertically swingable auger support disposed below the frame and movable up to the frame to permit the frame to be transported in a convenient manner.

-A further object of the present invention is to provide a boring machine including a wheeled frame and novel and improved corner jacks at the ends of the frame whereby the frame may be raised to a predetermined height.

A still further aim of the present invention is to provide a portable drilling apparatus that is extremely efiicient and reliable in use, strong and durable in operation, compact in structure, inexpensive to manufacture, service and operate, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the present invention in use;

Figure 2 is a side elevational view of the present invention in use and with part of the frame and carriage broken away to show the manner in which the auger support is pivoted to the carriage;

Figure 3 is a top plan view of Figure 1;

Figure 4 is a side elevational view of the present invention in position for transporting;

Figure 5 is a fragmentary side elevational view of the present invention and showing the carriage moved to the forward end of the wheeled frame;

Figure 6 is a plan view of the invention and with parts of the side beams broken away for the convenience of explanation;

Figure 7 is an enlarged detail view partly in section and partly in elevation showing the manner in which the auger is connected to the transmission; and

Figure 8 is a perspective view of the crank handle used in the invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l0 represents an elongated wheeled frame including a pair of spaced parallel channel-shaped side beams I2 whose forward and rear ends are connected to each other by transverse beams l4 whereby the shape of the main portion of the frame will be substantially rectangular.

-A transverse axle I6 is disposed at the rear of the frame and supports rubber-tired wheels 18. The beam I4 at the forward end of the frame 10 supports a mounting plate 20 to which there is secured a rotatable and removable front wheel mount 22. A draw bar 24 is pivotally attached to the mount 22.

The forward and rear ends of the side beams l2 fixedly support vertical guides 26 in which tubular uprights 28 are slidably received. The lower ends of the uprights 28 support pressure plates 30 and the upper ends of the uprights 26 support guide pulleys 32 over which cables 34 are trained. Forward and rear cable drums 36 and 38 are mounted on the frame I!) adjacent the guides 26. The cables 34 are terminally attached to the drums and to anchor eyes 40 fixed to the side beams [2.

The drums 36, 38 each carry a ratchet 42 and the ratchets 42 underlie pawls or looking dogs 44 that are pivoted to the frame l0. Cylindrical studs 46 project horizontally from the frame l0 and these studs are so located that one stud will be disposed parallel to the axis of each drum 36, 38 and relatively close thereto. A crank handle 46 is provided for selectively rotating the drums 36, 38. One end of the crank handle 46 supports a gear 50 that will mesh with a selected one of the ratchets or gears 42 and this end of the crank handle is also provided with a socket that will receive a selected one of the studs 46.

Each of the uprights 28 is provided with a plurality of vertically spaced apertures 52. Pins 54 are received in selected apertures 52 and rest upon the guides 26 and the side beams [2 to retain the uprights vertically adjusted in the guides 26 after the uprights have been moved by rotating the drums 36, 38.

A carriage or framework 56 is mounted on the frame ID for sliding movement and includes rollers or wheels 56 that track in the side beams l2. The carriage 56 supports a power plant 69, preferably a diesel engine, whereby an auger 60 may be rotated.

Means is provided for moving the carriage between the ends of the frame I0. This means consists of a transverse roller or drum 62 that is disposed at the rear end of the frame I and which is rotatably supported on a pair of vertically disposed channel-members 64 that are fixed at their lower ends to the rear ends of the Side beams I2. The forward of the transverse beams I2 supports a pulley 66 over which there is trained a cable 68 that is terminally secured to the drum 62 and the carriage 56. A pair of cables 10 are terminal fixed to the rear portion of the carriage 56 and the drum 62.

An upper and lower pair of telescoped shafts I2 and I4, each composed of two sections connected by splines, are rotatably mounted on the upper ends of the channel-members 64. The upper shaft 12 supports a sprocket 16 that is connected to a sprocket 18 On the drum 62 by a sprocket chain 80. One end 14a of the shaft 14 projects outwardly from one of the members 64 and supports a pinion 82 that will mesh with the gear 50 on the crank handle 48. The socketed end of the crank handle 48 receives one end of a stud 84 that projects outwardly from one of the members 64. A gear connection is provided between the shafts I2 and 14 so that the same will rotate in unison.

A vertically swingable support 88 is secured to and depends from the carriage B and includes forward and rear frame members 90 and 92 that are pivoted at their upper ends to the carriage, as at 9|. The lower ends of the frame members 90 and 92 pivotally support a platform 94 on which there is mounted a well-known transmission 96 whose driven shaft supports a multiple pulley 90 that is connected to a multiple pulley I00 on the drive shaft of the power plant 59 by a plurality of pulley belts I02. A diagonal brace I04 is pivoted at its upper end to the frame member 92 and the lower end of the brace I04 terminates in a hook I06 for engaging a pin I08 at the lower end of the member 90 to prevent swinging movement of the support 88.

A cable drum or roller H0 is disposed transversely of the frame I0 and is slidably and rotatably mounted on the side beams I2. A cable H2 is terminally fixed to the drum H0 and the forward end of the support 88. A crank handle H4 is fixed to one end of the drum IIO whereby the drum may be rotated to wind the cable II2 thereon and raise the support 88 when the hook I06 is removed from the pin I08.

The driving shaft of the transmission 96 supports a flexible coupling II6 including a splined sleeve II8 that received the splined end I20 of a socket member I22. The outer end of the member I22 is formed with a multi-sided recess or socket I24 in which the multi-sided end I26 of the auger 60 is held by a set screw I28.

In practical use of the present invention, the machine is pulled by a towing vehicle over a ditch D and a plank P is placed over the ditch and beneath the plates 30 of the rear uprights and a pair of blocks B are placed under the plates 30 of the forward uprights.

The uprights 28 are then lowered by the crank handle 48 or by releasing the dogs 44 and then rotating the drums 36 by the crank handle 48 until the frame ID has been lifted a desired height. Then the pins 54 are inserted into place.

The drum H0 is rotated to lower the support 08 and the auger 60 after which the hook I 08 is engaged with the pin I08 to hold the support 88 against swinging movement. The shift lever L of the transmission is in neutral. The crank handle 48 is employed as the starting crank for the power plant and is manually engaged with the starting shaft S of the power plant and is actuated to start the power plant after which the lever L is moved to drive the auger forwardly. As the auger digs into the dirt and moves forwardly, the carriage 56 also moves forwardly.

When the lever L is shifted to its reverse position, the auger will move rearwardly causing the carriage 56 to move rearwardly on the frame I0.
